List schemas, optionally filtered by zone.
/schemas [<zone>]## Overview `/schemas` lists schemas across the catalog. With no argument, returns every schema in every visible zone; with a zone name, scopes the listing to that zone. ## Behavior - Catalog-backed; requires control-plane auth. - Each row is a drill-in to `/describe <schema>` for a detailed view of that schema and its tables. - The argument is the zone NAME, not a pattern. For fuzzy discovery, use `/docs schema <pattern>` or `/describe` against a partial name.
